How can I replace value in a php file?

Hi,

I want to change a value in a php file which will come from DB.

I have two files, fun.php and cons.php. In fun.php, i have a query from which i get

$rows_col = $rw['rows']; //it shows 20.

PHP:

In the cons.php, i have a line (line#23, total lines - 39)

define("NUM_ROWS", 5);

PHP:

My question is, how can i replace 5 with the value of $rows_col? Any good solution please?

Thanks

 

cons.php:

First line of cons:

include("rute_to_your_file/fun.php");
define("NUM_ROWS", $rows_col);

Code (markup):

 

thanks, but is there any other way of doing this? Can i do it using fwrite, or str_replace?

 

ok, i have solved the problem. Thanks for your effort.
